Sean Stewart began training Brazilian Jiu Jitsu under Professor David Ruizin 2004 and has been studying the art with dedication ever since. As a 2018 IBJJF Denver International Open Jiu Jitsu Championship Gold Medalist – Black Belt; a 2016 Fight To Win Pro18 Superfight Victor – Black Belt; a 2012 NAGA Colorado No-Gi Grappling Champion – Expert Division; and winning 1st Place Gold at a number of tournaments in Colorado, not only has Sean learned to perform the techniques of Brazilian Jiu Jitsu against live, uncooperative, fully resisting opponents, but he has been taught specifically how to teach the art of Brazilian Jiu Jitsu by Professor Ruiz, just as Professor Ruiz was specifically taught how to teach the art by Rorion, Royce, and Helio Gracie.
